Rocker David Bowie and TV mogul Oprah Winfrey reportedly helped Tina Turner celebrate her recent nuptials to her longtime partner during a lavish party in Switzerland on Sunday. The What’s Love Got to Do With It hitmaker, who became a Swiss citizen in April, wed German record executive Erwin Bach during a discreet civil ceremony at the town hall in Kusnacht last month. And to mark the occasion, the newly-weds opened up their manor on the banks of Lake Zurich to around 120 people, including composer Sade Adu and DJ BoBo, for a special Buddhist bash. Turner was previously married to her musical partner Ike Turner for 14 years, but the stars divorced in 1978.
